Crown wheel and pinion set with a 4.75:1 final drive ratio for the front differential, long nose differential configuration. Tooth count is 38 on the crown wheel and 8 on the pinion.

The crown wheel and pinion form the final drive stage within the differential housing. The pinion is driven by the propshaft and turns the crown wheel, transmitting drive through 90 degrees to the differential carrier and on to the halfshafts. The lower ratio reduces the overall gearing between gearbox output and road wheels, which is commonly used to compensate for an increased tyre diameter. Front and rear differentials must run the same ratio.

Crown wheel and pinion are lapped together as a matched pair and must be fitted as a set, with pinion depth, bearing preload and backlash set on installation.

Frequently asked questions

What is the KAM546 crown wheel and pinion set for?
It's a 4.75:1 ratio crown wheel and pinion for the front differential, long nose configuration, with 38 teeth on the crown wheel and 8 on the pinion.
Why would I choose the 4.75:1 ratio over the standard ratio?
A lower ratio like 4.75:1 reduces the overall gearing between the gearbox output and road wheels, which is commonly used to compensate for larger-diameter tyres. It's a common upgrade on lifted or off-road-focused Defenders and Discoverys.
What's the difference between KAM546 and KAM548?
KAM546 is the long nose diff version of the 4.75:1 ratio, fitted to Defender, Discovery 1, Discovery 2, and Range Rover Classic. KAM548 is the short nose Wolf diff version for Defender and Range Rover P38, supplied for front and rear. Fit the version that matches your differential type.
Which vehicles take the KAM546 front crown wheel and pinion?
Fits the Defender, Discovery 1 (1989-1998), Discovery 2 (1998-2004), and Range Rover Classic (1970-1994) front axle, long nose differential, at 4.75:1.
